class_docstr: **Bases:** :class:`GraphicsObject <pyqtgraph.GraphicsObject>`
  
  Used for marking a horizontal or vertical region in plots.
  The region can be dragged and is bounded by lines which can be dragged individually.
  
  ===============================  =============================================================================
  **Signals:**
  sigRegionChangeFinished(self)    Emitted when the user has finished dragging the region (or one of its lines)
                                   and when the region is changed programatically.
  sigRegionChanged(self)           Emitted while the user is dragging the region (or one of its lines)
                                   and when the region is changed programatically.
